Certain early neuroimaging findings are independent predictors of clinical outcome in acute basilar artery occlusion. These imaging findings may serve as important baseline imaging characteristics as well as subgroups in future randomized controlled trials. The purpose of this review is to review and compare early neuroimaging findings seen on non-invasive cranial imaging that predict clinical ...

INTRODUCTION We present a rarely seen case of cerebral infarction due to intracranial dolichoectasia coexisting with spontaneous dissection of the basilar artery. A definition of dolichoectasia, its pathology, and imaging findings, as well as the clinical management and prognosis are briefly reviewed. CONCLUSION We discuss in general terms the diagnosis of basilar artery dissection and its pr...

A 43-year-old patient with a basilar apex aneurysm had a 4.5-mm x 14-mm Enterprise stent placed from the midbasilar artery to the left P1 segment of the posterior cerebral artery. The patient experienced vertigo 4 months after stent placement and 1 week after stopping clopidogrel. At 5 months postembolization, angiography showed stent migration into the proximal basilar artery. This is the firs...

Basilar artery ectasia may be associated with trigeminal neuralgia as a consequence of trigeminal nerve compression by the aberrant artery. The case histories are presented of four patients, investigation of whom demonstrated the presence of an ectatic basilar artery thought to be the cause of facial pain. The value of intravenous digital subtraction angiography in the investigation of this con...

INTRODUCTION Acute occlusion of the basilar artery is a neurological emergency that has a high risk of severe disability and mortality. Delayed thrombolysis or endovascular therapy has been performed with some success in patients who present after 3 hours of symptom onset. Here we present the first case of delayed intra-arterial thrombolysis of a basilar artery thrombosis associated with a larg...

In the present study, we investigate the possible role of protein kinase C (PKC)-dependent smooth muscle contraction in cerebral vasospasm following subarachnoid hemorrhage (SAH), employing the beagle "two-hemorrhage" model. The occurrence of chronic vasospasm was angiographically confirmed on day 7 in the basilar artery, which was exposed via the transclival approach. The artery was superfused...

BACKGROUND AND PURPOSE We postulated that some abnormalities in cerebrovascular function after subarachnoid hemorrhage (SAH) may involve underlying alterations in K(+) channel function. Thus, using pharmacological inhibitors, we assessed the influence of SAH on function of 2 types of K(+) channel in regulation of basilar artery diameter in vivo and membrane potential (E(m)) in vitro. METHODS ...

BACKGROUND AND PURPOSE Compromise of perforating branches of the basilar artery resulting in brain stem infarctions has been described as a major complication of intracranial stent placement for basilar artery stenosis or after implantation of endovascular flow diverters. Descriptions of pontine arteries are mainly based on examinations of injection specimens; however, there is a lack of consis...

We describe a patient who underwent intracranial angioplasty and Solitaire stent placement for recanalization of a vertebrobasilar artery occlusion 2 months after symptom onset. Computed tomography angiography and digital subtraction angiography showed that both vertebral arteries and the proximal basilar artery were occluded. Balloon angioplasty was performed on a segment of the occluded left ...

In this article we present an 80 year old female patient with an unruptured giant aneurysm of the basilar artery presenting with posterior circulation ischemic symptoms. Angiography and CT revealed giant basilar aneurysmal dilatation with severe and wide intracranial arteriosclerosis. We described the uniqueness of this case. Giant basilar aneurysm is associated with various complications parti...
